This is not a direct deal, but a deal enabler. Costco upon occasion gets some really good deals on camera gear, typically specific kits and bundles. Case in point, a few days ago they had an online super-bundle special on the K-30 (expired now). Some of the specials are online, some of the specials are in their brick and mortar mega-warehouse-stores. If you are not a Costco member, you can still buy, but you have to pay a 5% non-member surcharge. For more expensive camera gear, this surcharge is close to the annual Costco membership fee. So if you are a regular electronics shopper, a Costco membership might be more beneficial.
With that as a semi-necessary preface, there is a special promotion for new Costco memberships. The membership prices are the same, but you can get these freebies: 48 AA Kirkland brand single-use batteries, 35pk of drinking water (great for outdoorsy photographers), and a rotisserie chicken (if you are vegan/vegetarian, perhaps you can co-ordinate with a local shelter or food bank and deliver it to them at lunch/dinner time) [or you can use it to practice food photography].
